Maybe-expression
Fixtype of optional Syntheto expressions.
This is an option type introduced by fty::defoption.
Note that defoption is just a wrapper for fty::defflexsum, so there are :none and :some member
types, a case macro, and so forth.
Member Types
- :none → maybe-expression-none
- Represents that no maybe-expression is available, i.e., Nothing or None.
- :some → maybe-expression-some
- An available maybe-expression, i.e., Just val or Some val.
